CLOSURE FOR BOTTLES, JARS, AND THE LIKE.

Application filed October 11, 1928, Serial No. 311,896, and in Germany March 29, 1928.

My invention relates to improvements in closures for bottles, jars, and the like, and more particularly in closures of the type comprising a cap fixed to the bottle or jar by embracing the mouth thereof or a rim formed around the said mouth and a packing disk held in position on the mouth by the cap. The object of the improvements is to provide a closure of this class which is provided internally with a suitable mark, trade mark or other indication showing the origin of the contents of the bottle. IVith this object in view my invention consists in providing the packing disk with a tag or label having the said inscription printed or otherwise applied thereon.

For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawing in which the samereference characters have been used in all theviews to indicate corresponding parts. In said drawing,

Fig. l, is an elevation showing a top part of a bottle provided with a closure in the form of a cap,

Fig. 2, is a sectional elevation showing the cap detached from the bottle,

. Fig. 3, is a bottom view of Fig. 2, and

ig. 4, is a sectional elevation showing a modification of the cap.

In the example shown in the drawing the closure consists of a cap a of metal having a downwardly directed flange which is corrugated around its circumference so as to embrace a rim formed around the mouth of the bottle as is known in the art. Internally the said cap is provided with a packing disk 6 of a suitable artificial material other than cork, which disk is pressed on the mouth of the bottle by the cap a. To the packing disk Z) a one-colour or multi-colour tag or label a is fixed by cementing or otherwise, which tag or label is provided with a suitable inst-ription such for example as a firm name, a trade mark, a trade-name, andthe like showing the origin of the contents of the bottle. By being disposed within the closed bottle e and between the mouth thereof and the cap, the tag or label can not be removed, spoilt or otherwise injured, and it keeps its original appearance until the bottle is opened.

In Fig. 4 I have shown a modification in which the label a which is fixed to the outer face of the packing disk 6 is coated by means of a'suitable protective disk d made from transparent material which is not affected by the contents of the bottle and which does not in any way affect the character, the flavour or the taste of the said contents. A suitable material is for example a film made from or conmrising nitro-ccllulose.

In another modification the label 0 is embedded within the protcctive disk d, or it is directly applied to the packing disk by means of a dye-stuff mixed with a suitable material having the above-named properties.

By means of the closure provided with one of the aforesaid inscriptions the origin of the contents of the bottle or jar can be safel identified. Before opening the bottle the inscription can be inspected through the wall or the bottom thereof, and after opening the bottle the inscription is clearly visible, so that the contents of the bottle are identified without special examination.

I claim:

1. The herein described bottle closure comprising a cap adapted to embrace the mouth of the bottle, a packing disk within said cap made from artificial material, a mark applied to the outer side of the said packing disk, and a transparent coating of indifferent material covering the said mark.

2. The herein described bottle closure comprising a cap adapted to embrace the mouth of the bottle, a packing disk within said cap made from artificial material, a layer of transparent and indifferent material applied to the outer side of said packing disk, and a label embedded in said layer.

3. The herein described bottle closure comprising a cap adapted to embrace the mouth of the bottle, a packing disk within said cap made from artificial material, and an inscription made from a dye-stuff and a substance which is transparent and indifferent and applied to the outer face of said packing disk.

In testimony whereof I have affixed my signature.

EWALD GOLTSTEIN.
